My DD aged 8 is very interested in when her boobs will grow, when she'll get pubic hair and other puberty related things. We talk about it openly but I'd like to get her a book so she can refer to it when she wants to. I've had a good look at the library and online and they all seem to cover sex and baby making aswell. I don't mind her knowing about sex and how babies are made but they all go into massive detail about other topics such as masturbation and one even talked about being sewn up after you have a tear during childbirth!! They seem aimed at a slightly older audience.
Does anyone know any good fairly basic level books that cover just the basics to get us started?
